OF NE\V YORK, N. Y., A CORPORA- DOGGlNG MECHANISM FOR SAFE OR VAULT BOLTING MECHANISMS.

SPECIFICATION forming part of Letters Patent No. 788,085, dated April 25, 1905.

Application filed February 4,

Be it known that we, ORLANDO 1V. Bnnnnn, residing at Princess Bay, Staten island, in the county of Richmond and State of New York,

and l-lnxnr Dmnxo HIBBARI), residing at Plainlield, in the county of Union and State of New Jersey, citizens of the United States. have invented certain new and useful improvements in Dogging Mechanisms for Safe or Vault Mechanisms, of which the following l is a specification.

This invention relates to the bolt mechanism of safes or vaults, it more particularly relating to means for doggingsuch bolt mechanism,

I5 the object of the invention being to provide improved means for directly dogging the bolts, thereby to prevent the retraction of such bolts when the operating or actuating means therefor is disassembled or disconnected by force therefrom.

A further object of the invention the provision of depressible boltlocking means thrown into operation on the displacement or separation of a part of the door proper-----as, for instance, the back plate.

in the drawings accompanying and forming a part of this specification, Figure l is an interior view of a safe or vault door having a part of its back plate removed with this improved doggingmechanism in position. Fig. 2 is a cross-sectional view thereof, taken in line u (I, Fig. 1. Fig. 3 is an enlarged detail view of a part of one form of this dogging mechani ism. Fig. T is a detail sectional view of a part thereof. Fig. 5 is an enlarged detail view of another form of such dogging mechanism. Fig. 6 is a sectional view thereof in its locking position. Fig. 7 is a detail view of the locking-ring shown in Fig. 5. Figs. 8, 9, and ll) are detail views illustrating one form of spring which may be used to maintain the ring in its bolt-dogging position.

Similar characters of reference designate like parts in all the figures.

This bolt-dogging mechanism may be used 1 in connection with variousforms ofdoors. The l 1904. Serial No. 191,924.

one shown is an integral door 2 comprising a body 3 and a flange l, provided with a back plate 18, said flange having a suitable number of bolt openings In practice the door will preferably be made of manganese steel. Cast with the body of the door is a centrally-located boss 6, against which it is intended the in ner ends or shanks of the bolts will engage when such bolts are protracted. The operating means may be any suitable means adapted for the purpose, but is shown herein comprising a worm-wheel member or disk 7, to which the innerends 8 of the bolts are pivoted. This worm-wheel 7 is in engagement with a wormshaft 9, carrying a loosely-mmmted bevel-gear 10,having a hub 12, formed as a clutch member, in position to be engaged by a splinedclutch member 11), mounted upon said shaft and connected with one or more combination-locks 14:, shown herein astwo. A bevel-gear 15, mounted on the inner end of a spindle 16, passing through the body of the door, is in mesh with the loosely-nmunted bevel-gear 10, whereby when the clutch members are in engagement the worm-shaft can be turned to rotate the worm-wheel to rock the bolts, and thus shift them radially in a manner that will be readily understood.

The worm-dusk is shown mounted upon a stud 17, carried by a back plate 18, being held thereon by a suitable washer l9 and bolt 20.

Owing to the fact that it is not practicable to swing or rock the bolts into such position that they will be in a dead-center position with the axis of the door, it is desirable that such bolts be dogged to prevent them from being retracted should the back plate be forced off, in which event it would carry with it the worm-wheel, and thus leave the bolts unconnected with the operating or actuating mechanism. To prevent the retraction of the bolts, dogging mechanism is provided, which in the preferred form thereof herein shown and described comprises a member shown in the form of a ring 21, located in a recess or channel" formed in the bodyof the door. hen

the body of the safe is made of hard and unmachineable metal, such as manganese steel, this recess may be formed during the casting of the door. This ring in the form shown in Figs. 2, 3, and 4 comprises a bevel-faced or wedge-shaped ring 23, adapted to cooperate with a beveled or wedge-shaped recess 24, formed at one side of each of the bolts. This ring is maintained within its recess, so as to permit the ordinary shifting of the bolts by a suitable meanssuch, for instance, as stems" shown herein in the form of sleeves 25, each having one end in engagement with the outer face of the ring and the other end in engagement with the back plate. Each sleeve islocated upon a screw or bolt 26, projecting from the back plate through the sleeve and into the ring. By this means the ring is normally maintained in its recess out of engagement with the bolts when the back plate is bolted in position. Should, however, this back plate be forced off by explosives or other means, the bolts 26 act to pull the ring out of its recess and in to the recesses of the bolts, thereby interlocking the parts and locking the bolts against retraction. This may also be assisted by means of one or more springs, which in Figs. 1, 2, and 3 are shown as flat springs 27, the tendency of these springs being to throw the ring into engagement with the bolt and to maintain it into such engagement. Instead of utilizing this form of spring for holding the ring inits bolt-clogging position a different form may be used. In the form shown in Figs. 8, 9, and 10 a notch or opening 28 is providedin the side wall of the recess, being located adjacent to the free end of the spring 29, so that when the ring is pulled into engagement with the bolts this spring will enter such notch or recess and maintain the ring in its bolt-clogging position, as illustrated in Fig. 9. In another form thereof this lockingring is shown as a fiat member recessed at those points 30 thereof contiguous to the bolts, each of which is also recessed, as at 31, to interlock with such ring, so that when the ring engages the bolts it overlaps such bolts at the sides thereof, while the bolt in turn overlaps the sides of the ring, so that the bolts are locked against both longitudinal and sidewise movement. The same means may, however, be used for shifting the ring into its dogging position. To prevent the shifting of this recessed ring and maintain it in position to properly engage the bolts at the desired time, it may be held against movement by means of a forked arm 32, attached to the ring and cooperating with a pin 33, located on the door-body. It of the bolts.

erable to form or unite the inner ends of the bolts, so that one could not move independently of its companion bolts. In some forms thereof the depressible dogging means could be used in connection with other shapes of door than circular.

This improved dogging means, it will be seen from the foregoing, comprises depressible means normally held under depression and in the present instance within and below the surface of the door-body, a recess being formed in the metal thereof for the reception of this means.

Having thus described my invention, I claim 1.
